ABSTRACT
Virtualization has become absolute mainstream in most organizations. Snapshots play a large part in virtual infrastructure protection that could arguably say a full machine snapshot is the holy grail of system administration. At any point the system administrator might choose to roll back to either of those snapshots and it would be perfectly valid to do so but application logs and operating system logs stored on the other filesystems will no longer be consistent with the state of the data region. Virtualization therefore can allow for considerably easier whole-system snapshot scenarios. Backup systems supporting fine-grained control over what files or data on a client are or are not backed up will perform no differently with client software installed within a virtual machine as they would within a physical host. Image-level recovery of virtual machines can be particularly efficient when there are a large number of files in the virtual machine.
